Supertech Toyota 2JZ 87mm 34mm CH 86mm Stroke -7.2cc Dish 9.5:1 CR Piston - Set of 6 (Excl Rings)

If you're rebuilding the engine in your Toyota 2JZ, these Supertech forged pistons are a solid choice for handling increased power. This set is designed for the 2JZ engine, featuring an 87mm bore and a 9.5:1 compression ratio, which is a popular choice for many performance builds. The 34mm compression height and 86mm stroke are specific to the 2JZ platform, ensuring proper fitment within the cylinder block and connecting rod assembly.

These pistons are forged from high-strength aluminum alloy, a common practice for performance pistons because it offers a good balance of strength and weight. Forging creates a denser, more durable grain structure compared to cast pistons, making them more resistant to the extreme pressures and temperatures found in a high-performance engine. The -7.2cc dish in the piston crown is designed to achieve the 9.5:1 compression ratio when paired with the stock 2JZ cylinder head volume. This specific compression ratio is versatile, offering a good compromise between low-end torque and high-RPM power, and is suitable for naturally aspirated or boosted applications.

This set includes six pistons, but please note that piston rings are sold separately. You'll need to select the correct ring set that matches the piston bore and the piston ring groove dimensions. It's also important to note that these pistons are not CARB approved and cannot be shipped to California. Always refer to the manufacturer's installation instructions for proper assembly and torque specifications when installing these pistons into your engine.
